W40.8: Explosion of other specified explosive materials
W40.8 is a non-billable header ICD-10-CM code for explosion of other specified explosive materials. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category W40

- D
- subsequent encounter

Excludes1 inherited from the categories above W40.8
